Anybody put a 4.0L in an 82 CJ7?

I am going to help a buddy upgrade his 82 CJ7. I have scored a 4.0L and I am going to rebuild it as a 4.7L stroker.

My first question has to do with getting a high pressure fuel system. Did you go with an external pump and a return line, or did Jeep have a compatible high pressure tank with a return on a later or different model?

To keep things cheap and simple, I am going to keep the T5 / D300 combo. That means that I need to mount a CPS. I figured I would pull the existing bell housing and machine it for the new CPS. Anybody ever done this?

I have a cnc mill and can build up the aluminum before machining if needed. Anybody ever done this or have a good link. Dimensions would be nice, but I can pull them off of an AX15 if necessary.

What did you do for a clutch disk? Does the CJ setup work with an AX15 clutch disk?

Go with the AX15 and keep life simple.

Novak makes no adapter as the T5-4 is a POS.

OK, since you're the expert, if I switch the tranny, then I have to switch the tcase.. That means a custom cross member and different drive shafts.

He doesn't do any serious off-road or hotrod it.

I am just looking for a simple fuel solution.

Back to my original statement..........

You'll have a harder time modifying the bell to accept the CPS than you will modifying a cross member.
The answer is to stick with an AX15.

As to the fuel system.......inline regulators are about $100 last time I looked, mount to the frame rail and return to the tank.....simple enough.

I have my own shop and mill and 40+ years of experience. That mod is pretty easy. Fabbing a cross member isn't hard, just having the drive shafts modified gets pricey.

Personally, there is no way I'd do any amount of work to keep a T5 behind anything, especially a stroker. By the time you figure out the sensor stuff and the flywheel/clutch, you'll have an old, weak, one-off transmission.

With an AX15 at least you'll have some strength to show for your troubles. Modding driveshafts really shouldn't cost much, less than the headaches you'll go through making a T5 work then promptly needing to replace it.

My local driveline guy charges under $200 to make those kind of changes when I need them.

Re: Anybody put a 4.0L in an 82 CJ7?

There is an off the shelf fuel pump that was recommended to me. E2000 I believe it was. I would use an OBD1 fuel rail and computer. Fuel regulator is on the rail. So all you would need is a return line into the existing fuel tank I believe. Of course I'm not going on any experience just theory.

Re: Anybody put a 4.0L in an 82 CJ7?

If you do the Hesco kit with the harmonic balancer CPS, make sure that its clocked right and loctite the bolt. I spent a long time troubleshooting a car with one of those kits to discover that there was play in the assembly and the timing was not only off, but would change with hard bumps.

Good to know...did the system work well for you, I'm spending alot of time and money to make sure this CJ is perfect.

Re: Anybody put a 4.0L in an 82 CJ7?

I didn't install it, and after getting it running right never saw the car again, but driving it around for a couple of days it seemed to do pretty good. Stock renix 4.0 in a CJ5 with the CJ's manual trans. If I were doing one I'd probably want to keep the auto.
